Know about Epilepsy

Epilepsy is a brain disorder in which a person has repeated seizures (convulsions) over time. Seizures are episodes of disturbed brain activity that cause changes in attention or behavior.

A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain.
Generalized tonic - clonic seizur :A generalized tonic-clonic seizure is a seizure involving the entire body. It is also called a grand mal seizure. The terms "seizure," convulsion," or "epilepsy" are most often associated with generalized tonic-clonic seizures

Causes, incidence, and risk factors

Generalized tonic-clonic seizures may occur in people of any age. They may occur once (single episode), or as part of a repeated, chronic condition (epilepsy).

Symptoms

Many patients with generalized tonic-clonic seizures have vision, taste, smell, or sensory changes, hallucinations, or dizziness before the seizure. This is called an aura.

The seizures usually involve muscle rigidity, followed by violent muscle contractions, and loss of alertness (consciousness).Other symptoms that occur during the seizure may include:

• Biting the cheek or tongue

• Clenched teeth or jaw

• Loss of urine or stool control (incontinence)

• Stopped breathing or difficulty breathing

• Blue skin color

After the seizure, the person may have:

• Normal breathing

• Sleepiness that lasts for 1 hour or longer

• Loss of memory (amnesia) regarding events surrounding the seizure episode

• Headache, drowisiness and confusion
  

• Weakness of one side of the body for a few minutes to a few hours following seizure (called Todd's paralysis)
